RGB-LED-controller-: common questions

What microcontroller does the RGB-LED-controller- use?

The RGB-LED-controller- is built around the ATTINY25-20S, from the AVR/Arduino family.

How big is the RGB-LED-controller- PCB?

The RGB-LED-controller- measures 50.1 × 46 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RGB-LED-controller-?

24 components, from 14 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the RGB-LED-controller- design files?

From the MohamedHassanExp/RGB-LED-controller- repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the RGB-LED-controller- design in my own project?

Yes, under the terms of its MIT license, which MohamedHassanExp chose for the repository.

Can I test firmware for the RGB-LED-controller- without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
